How to Disconnect Water Supply Lines From Bathroom Sink

Disconnecting water supply lines from a bathroom sink is a relatively simple plumbing task that can be completed in a few minutes with the right tools. Whether you're replacing a faucet, repairing a leak, or remodeling your bathroom, knowing how to disconnect water supply lines is an essential skill.

Before you begin, gather the necessary tools: a pair of adjustable wrenches, a bucket or towel to catch any water that spills out, and a flashlight if necessary. Turn off the water supply to the sink by closing the shut-off valves located under the sink. Open the faucet to release any remaining water in the lines.

Locate the water supply lines connected to the bottom of the sink faucet. There will typically be two lines: one for hot water and one for cold water. Each line will have a nut that connects it to the faucet. Place one adjustable wrench on the nut and another on the faucet body. Turn the wrench on the nut counterclockwise to loosen it. Avoid putting too much force on the faucet body, as this could damage it.

Once the nut is loose, carefully unscrew the water supply line from the faucet. Hold the line steady with one hand to prevent it from spinning. If the water supply line is old or corroded, it may be difficult to remove. Apply some penetrating oil to the threads and let it sit for a few minutes before trying again.

Repeat the process for the other water supply line. Once both lines are disconnected, you can proceed with your plumbing repair or replacement.

When reconnecting the water supply lines, make sure to hand-tighten the nuts as much as possible. Use the adjustable wrenches to tighten the nuts further, but avoid overtightening, as this could damage the lines or the faucet.
